Season 7EditIn Out With The Old, Sam and Dean uncover a pair of cursed ballet slippers that are responsible for the death of a ballerina. They save the slippers' next intended victim, and trace them back to an antique shop that was owned by a hunter who died a week earlier. She kept at least four curse boxes in a safe, which was also marked with sigils, but her son, unaware of the significance, opened the boxes and sold the objects inside. Sam and Dean are able to recover all the objects and return them to the boxes and the safe. They take the safe with them in a trailer when they leave.
In Book of the Damned, it is discovered that the Men of Letters created a special curse box and stored it among the Styne Family files. The curse box has been branded by various Enochian sigils. It's later picked up by Sam and Dean who bring it along with them. It proved very effective in hiding the book and suppressing its power from Jacob Styne. At the end of the episode, Sam uses it to safe handle to Rowena.
- The idea for the curse box may have come from the legend of Pandora's Box, a box that holds all the evil and all the diseases in the world, until - once opened - it releases all this evil upon the world, leaving only Hope behind.
